Fundraising Plugin not going to Paypal

I installed the fundraising plugin yesterday as an alternative to the Easy Wordpress Donations plugin. This plugin seemed easy enough to set up, but I am having issues. I followed the instructions via the manual to set up "Simple Donations" via Paypal, pointing the IPN to the given address and so on, but when I try a test donation, I am taken directly to the /pledge/ page, where it says, "Your pledge is almost complete!" with a button that says "Complete pledge." I click the button and it takes back to the /pledge/ page but this time with the same form I filled out before...

Not sure what the issue is, but it's not working correctly at all... what information is needed to troubleshoot this thing?

The url for my test fundraiser is http://www.minutemenministries.org/fundraisers/minutemen-headquarters-project/
